Decent window at best. Sashes operate very smoothly. I don't care for the appearance of the beveled screentrack exterior personally, they could have done a lot better with that. A window for the North East with a SHGC of .19 would not be my first choice. Any sales rep or company that trains their guys/gals to promote 50% energy savings claims should have Terminators target them for good old 80's action movie style destruction.
The fact that this windows is sold by by the company that sets the installation standard
that claims 50% energy savings is reason enough for me to stay away from them.
I don't care if the window was the greatest thing since sliced bread. If you make those kind of unenforceable claims, all the while knowing that the customer has very little recourse and will never get to that number, your position of authority and honor are shot in my eyes.
booschang...you aren't going to claim that this window is going to save you 50% are you now?
As Delaware Mike mentioned, SHGC numbers are off for this area as well. At 0.19, that is not a good choice for Deleware.
Why are people quoting R-Values for frames anyway? That number is designed to confuse the customer into thinking that this if the R-Value of their window. While I acknowledge that an insulated, by air chamber or insulation (preferrably foam), is better, it is ultimately very little in the overall efficiency picture. Fiberglass resin frames are less insulated but their window performance is comparable and better than most of their vinyl counterparts.
Window R-Value is 3.85...why even throw out the R-12.6 number.
Fiberglass as and insulation is worthless for the most part. As soon as that fiberglass sags or looses contact with any part of the window, it is worthless. Again, putting it in there is misleading at best. If they want insulation, foam is the far better option.
